3 tickets at 20 gives "333…" instead of 60

Time: 0:00

BugFind the bug and fix the code

What it should do

tickets_total(count_text, price) works out the cost of a booking. The ticket count comes from a form as text. Example: tickets_total("3", 20) → 60.

What happens instead

tickets_total("3", 20) returns "33333333333333333333", the digit 3 twenty times.

def tickets_total(count_text, price):
    return count_text * price

Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).

This bug belongs to the type errors pattern

Totals that concatenate, sorts that put 10 before 9, comparisons that refuse to run.

Learn the type errors pattern Step through your own code

Spoiler: why this bug happens(try it first; the hints get warmer one at a time)

What went wrong: "3" * 20 repeats the text "3" twenty times. Python does not see it as maths.

The fix: return int(count_text) * price

Remember: form input is text. Convert it before doing maths.

The pattern behind it: type errors.
